Thermolite is a DuPont fabric made with hollow fibres that insulate without bulk. A midweight sock, these are a step up on summer socks as far as keeping your tootsies warm and they’ll still fit inside your race shoes.

• Hollow-core fibers trap air and allow greater insulation
• Also the larger surface area allows for faster evaporation by speeding moisture away from the skin to the surface.
